Final answer:
Masculinity may or may not be related to the male sex. Research on masculinity demonstrates that it is always held in opposition to "female." The drive to adhere to masculine and feminine gender roles continues later in life.
Step-by-step explanation:
Masculinity may or may not be related to the male sex (because, for example, women can "do" masculinity, too).
Research on masculinity demonstrates that “male” is not a stand-alone category but is always held in opposition to "female," even when women are not present.
The drive to adhere to masculine and feminine gender roles continues later in life. Men tend to outnumber women in professions such as law enforcement, the military, and politics. Women tend to outnumber men in care-related occupations such as childcare, healthcare, and social work. These occupational roles are examples of typical U.S. male and female behavior, derived from our culture's traditions.
